The most common graph for the
planet Pluto. This
planet is also symbolized by , , and . According to Bode's
in Group 17), the ninth
planet of the sun should orbit at a distance of about 40 earth-sun
distances from . Bode formulated his law in the
eighteenth century. But was not discovered until
1930. Pluto was found to orbit at approximately the Bode's law
distance from the sun (actually the average distance is 39.8 earth-sun
The planet's orbit is much more elliptic than those of most other known planets. Therefore, it sometimes takes only 13 years to move through one of the signs of the zodiac, while at other times it takes 31 years.
Pluto's orbit has an inclination of 17 degrees relative to the ecliptic (see in Group 38 for facts about the ecliptic). In theory Pluto was discovered around the year 1905 by Percival Lowell, a US astronomer. The most commonly used graph for the planet, , is based upon his initials. From irregularities in Neptune's movements, and mathematical calculations, Lowell predicted that a small planet would orbit at a distance of approximately 40 earth-sun distances, and that this planet's orbital period would be approximately 282 years. The actual orbital period of Pluto is 248 years. Apart from this discrepancy, Lowell's predictions were quite accurate.
Pluto's mass is just an eighth of the mass of our moon. Most of this planet's physical characteristics are unknown, but it is supposed to have a surface temperature of minus 200 degrees Celsius.
In astrological symbolism represents death and rebirth, total transformation, atomic energy, ruthlessness, dictatorships, large organizations and competition. Astrologers in the West claim Pluto to be the ruling planet of Scorpio, ; that sign formerly was thought to be ruled by Mars. The US astrologer Alan Oken suggests that is merely a higher octave of . Mars breaks down form, he claims, but transforms its very atomic structure. The planet is the aggressive and emotional energy behind wars, he says, but the planet represents the ultimate destruction of the atom bomb. signifies the passion in sexuality, but represents the orgasm. is the anger that makes the soldier pull the trigger, but is the force that separates the soul of the man who is shot from his body, Oken says.
The astrological significance of a planet is affected by the situation of the society that discovers it at the time of its discovery. When was discovered in 1930, the criminals had the upper hand in the United States thanks to the stupid prohibition of alcoholic beverages. Fascist regimes were appearing in Italy, Germany, and the Soviet Union. That time in the present cycle of human civilization was also the time of the Great Depression, and the beginning of the nuclear age.
At its visual discovery in 1930 was passing through the sign of Cancer, . At the time of the final translation of this dictionary of ideograms into English, Pluto is leaving the sign it rules, Scorpio, and entering Sagittarius, the sign of the Archer projecting his arrow to distant futures.
The planet is named after the Roman god Pluto, guardian of the underworld and the god of the kingdom of death. Hades was the corresponding Greek god, and the underworld was later called Hades after its ruler. In Greek mythology, however, Hades in the fifth century B.C. merged with Pluton, the ruler over riches and buried treasures, and it is from this that the word plutocrat is derived, meaning a regime in which the rich rule the masses.
It should be added that a lot of astrologers believe it to be significant that was discovered on the longitude of 20 degrees , and that the first atom bomb detonation on earth (known to us) occurred at the exact moment when the planet , Saturn, reached this longitude in 1945.
Mundane astrology has not yet associated to specific countries and cities. Pluto is, however, supposed to rule over persons who work underground, for instance in mines or subways, but also those who, figuratively speaking, work underground, such as mafiosi, terrorists, etc. is associated with espionage, detective work, and healing.
Finally it should be mentioned that most astrologers agree that is associated with the workings of the deepest, subconscious psychological processes in humans.
The sign was used far earlier than the discovery of the planet Pluto. Diderot, in his Encyclopedia from the eighteenth century records as a sign for lamps.
